Answer:
x = 2√7 or 5.2915
Step-by-step explanation:
x^2 + 28 = 0
first get the variable by itself by subtracting the 28 from both sides. 28-28 cancels and 0-28=-28.
now you have
x^2 = -28
take the square root of x^2 to cancel out the exponent, and then do the same to the other side,
x = √28
x = 2√7 or 5.2915
